Omnia Audio Omnia A/XE - Manual (Page 54)

Drive: The sets the audio level that enters the WB-AGC. Increasing the Drive will produce
more compression. This control is calibrated between –6dB and +6dB, and adjusts the signal
level into the Wideband AGC. It should be adjusted to net approximately 12dB of gain
reduction with typical programming. Too little gain reduction can defeat the “leveling”
function of the Wideband AGC. Too much gain reduction has little additional benefit.
Nominal gain reduction values for the Wideband AGC are between 10 and 15dB.
Release: Controls the speed of recovery for any given amount of gain reduction. Faster
action yields less dynamic range and the presence of more density to the audio. The Release
control sets the time constants in relative terms using Slow, Medium, and Fast. Because the
time constants are program-dependent, calibrating these controls in absolute time values
(ms/dB) would be useless—therefore we use simple terminology.
GATE: When set to ON, it will freeze the gain at the last level of processing action that
occurred before the audio signal fell below the threshold of operation. This control helps to
minimize “pumping”, and the increase of background noise during pauses in programming.
Clicking OK after adjusting any of the parameters in this section will save the change and
close the sub-menu.
Bass
This section contains the Bass EQ controls. In the Omnia A/XE’s unique signal processing
architecture, these controls are placed in their optimal position — just before the multiband
processor sections. Each of the Deep Bass and Phat Bass controls can boost the level up to
12 dB. Be careful here not to overdrive the following sections or over emphasize these lower
frequency ranges. When used properly this specialized low frequency enhancement tools
can deliver the thunderous bass and warmth that the Omnia is known for, and it can do so
without making the sound muddy.
